Anti-Mullerian hormone (AMH) in the Diagnosis of Menstrual Disturbance Due to Polycystic Ovarian Syndrome.

ABSTRACT: Introduction: Polycystic ovarian syndrome (PCOS) is a leading cause of female subfertility worldwide, however due to the heterogeneity of the disorder, the criteria for diagnosis remains subject to conjecture. In the present study, we evaluate the utility of serum Anti-Müllerian hormone (AMH) in the diagnosis of menstrual disturbance due to PCOS. Method: Menstrual cycle length, serum AMH, gonadotropin and sex-hormone levels, total antral follicle count (AFC), body mass index (BMI) and ovarian morphology on ultrasound were analyzed in a cohort of 187 non-obese women, aged 18-35 years, screened for participation in a clinical trial of fertility treatment between 2013 and 2016 at a tertiary reproductive endocrine center. Results: Serum AMH was higher in women with menstrual disturbance when compared to those with regular cycles (65.6 vs. 34.8 pmol/L; P < 0.0001). The odds of menstrual disturbance was increased 28.5-fold (95% CI 3.6-227.3) in women with serum AMH >60 pmol/L, in comparison to those with an AMH < 15 pmol/L. AMH better discriminated women with menstrual disturbance (area under ROC 0.77) from those with regular menstrual cycles than AFC (area under ROC 0.67), however the combination of the two markers increased discrimination than either measure alone (0.83; 95% CI 0.77-0.89). Serum AMH was higher in women with all three cardinal features of PCOS (menstrual disturbance, hyperandrogenism, polycystic ovarian morphology) when compared to women with none of these features (65.6 vs. 14.6 pmol/L; P < 0.0001). The odds of menstrual disturbance were increased by 10.7-fold (95% CI 2.4-47.1) in women with bilateral polycystic morphology ovaries than those with normal ovarian morphology. BMI was a stronger predictor of free androgen index (FAI) than either AMH or AFC. Conclusion: Serum AMH could serve as a useful biomarker to indicate the risk of menstrual disturbance due to PCOS. Women with higher AMH levels had increased rates of menstrual disturbance and an increased number of features of PCOS.

Project description:Anti-Müllerian hormone (AMH) is produced by granulosa cells of pre-antral and small antral ovarian follicles. In polycystic ovary syndrome (PCOS), higher levels of serum AMH are usually encountered due to the ample presence of small antral follicles and a high AMH production per follicular unit which have led to the proposal of AMH as a serum diagnostic marker for PCOS or as a surrogate for polycystic ovarian morphology (PCOM). However, heterozygous coding mutations of the AMH gene with decreased in vitro bioactivity have been described in some women with PCOS. Such mutation carriers have a trend toward reduced serum AMH levels compared to noncarriers, although both types of women with PCOS have similar circulating gonadotropin and testosterone (T) levels. This report describes a normal-weight woman with PCOS by NIH criteria with severely reduced AMH levels (index woman with PCOS). Our objective was to examine the molecular basis for her reduced serum AMH levels and to compare her endocrine characteristics to similar-weight women with PCOS and detectable AMH levels. Twenty normoandrogenic ovulatory (control) and 13 age- and BMI-matched women with PCOS (19-35 years; 19-25 kg/m2) underwent transvaginal sonography and serum hormone measures including gonadotropins, sex hormone-binding globulin, total and free T, androstenedione, dehydroepiandrosterone sulfate, estrone, estradiol and AMH. The latter was measured by ELISA (Pico-AMH: Ansh Labs, Webster, TX, USA). Women with PCOS and detectable AMH had higher serum AMH (10.82 (6.74-13.40) ng/ml, median (interquartile range)), total and free T (total T: 55.5 (49.5-62.5) ng/dl; free T: 5.65 (4.75-6.6) pg/ml) levels and greater total antral follicle count (AFC) (46 (39-59) follicles) than controls (AMH: 4.03 (2.47-6.11) ng/ml; total T: 30 (24.5-34.5) ng/dl; free T: 2.2 (1.8-2.45) pg/ml; AFC 16 (14.5-21.5) follicles, P < 0.05, all values), along with a trend toward LH hypersecretion (P = 0.06). The index woman with PCOS had severely reduced serum AMH levels (∼0.1 ng/ml), although she also had a typical NIH-defined PCOS phenotype resembling that of the other women with PCOS and elevated AMH levels. All women with PCOS, including the index woman with PCOS, exhibited LH hypersecretion, hyperandrogenism, reduced serum estrogen/androgen ratios and PCOM. A homozygous Ala515Val variant (rs10417628) in the mature region of AMH was identified in the index woman with PCOS. Recombinant hAMH-515Val displayed normal processing and bioactivity, yet had severely reduced immunoactivity when measured by the commercial pico-AMH ELISA assay by Ansh Labs. In conclusion, homozygous AMH variant rs10417628 may severely impair serum AMH immunoactivity without affecting its bioactivity or PCOS phenotypic expression. Variants in AMH can interfere with serum AMH immunoactivity without affecting the phenotype in PCOS. This observation can be accompanied by discordance between AMH immunoactivity and bioactivity.
